I encourage you to head over to Out of Ur to read their article The Hansen Report: Modern versus Postmodern Politics.
I think the writer of this article gives a good summation of how modern and postmodern views affect our interpretation of religion and politics. He states that the arguments of McCain and Obama, and the way in which they are argued, are very reflective of the growing pains that religion is experiencing today.
From the article :
Obama spoke with empathy about the personal effects of the current financial crisis on Main Street America. He advocated greater oversight for Wall Street. McCain, too, said he wants oversight, but he emphasized different reasons for the crisis. He spoke of individual greed and said the government needs to hold the failed executives accountable. As the debate progressed, McCain spoke passionately about members of Congress who perpetuate the "evils of this earmarking and pork-barrel spending." McCain underscored personal morals where Obama accentuated communal values.
McCain is a man of action and frank talk. Obama sees intrinsic value in engagement, which may even produce unexpected tangible consensus. You could plug in certain pastors and see the same differences.
